The fork truck has the advantages that in case of sudden power failure, goods can be handled, loaded and unloaded manually in a power-off working filed, and also has the advantages of dual functions, economy, simple and compact structure, good stability, light weight, flexibility, and good maintainability.
Description
Technical field
The utility model relates to the hydraulic forklift field, is specifically related to a kind of hand for fork truck, electric dual-purpose actuating unit.
Background technology
At present, existing hydraulic forklift is divided into manual, electronic two large series.Its principle of work be by outer application force by oily suction pumping cylinder in Hydraulic Station, then squeeze in clutch release slave cylinder, make goods lifting or decline.Although existing hand fork lifter energy-conserving and environment-protective, economical and practical, need manual operation, during the lot cargo loading and unloading, labor strength is large, easily is short of physical strength; And although electri forklift does not need manual operation, convenient and practical, in the situation that stop, short of electricity can not be used.
The utility model content
The purpose of this utility model is exactly to be divided into manual, electronic two large series at present existing hydraulic forklift.Its principle of work be by outer application force by oily suction pumping cylinder in Hydraulic Station, then squeeze in clutch release slave cylinder, make goods lifting or decline.Although existing hand fork lifter energy-conserving and environment-protective, economical and practical, need manual operation, during the lot cargo loading and unloading, labor strength is large, easily is short of physical strength; And although electri forklift does not need manual operation, convenient and practical, in the situation that stop, deficiency that short of electricity can not be used, and provide a kind of hand for fork truck, electric dual-purpose actuating unit.
The utility model comprises the fork truck body, it also has hand, the dual-purpose actuating unit of electricity, hand, the dual-purpose actuating unit of electricity is by fuel tank, oil main line, manual operation system, electric pump and oil cylinder form, the hydraulic fluid port of fuel tank communicates with oil main line one end, manual operation system is comprised of manual pump and Manual relief valve 4, the oil inlet of manual pump and oil outlet communicate with the oil inlet of oil main line and fuel tank by A pipeline and B pipeline respectively, on A pipeline and B pipeline, be respectively equipped with A check valve and B check valve, on the B pipeline, have drain tap, the drain tap of B pipeline communicates with fuel tank by the C pipeline, the C pipeline is provided with Manual relief valve, the import of electric pump and outlet communicate with fuel tank and oil main line by D pipeline and E pipeline respectively, on the E pipeline, be respectively equipped with C check valve and arm, the arm two ends communicate with E pipeline and fuel tank respectively, arm is provided with by pass valve.
Electric pump is motor and gear type pump, and the power take-off shaft of motor is connected with the gear type pump transmission.
The utility model advantage is: can have a power failure suddenly, not have electric work-yard by manual mode, portage to be loaded and unloaded.Dual-use is economical and practical; Simple in structure, compact, good stability; Light and flexible is maintainable good.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises the fork truck body, it also has hand, the dual-purpose actuating unit of electricity, hand, the dual-purpose actuating unit of electricity is by fuel tank 1, oil main line 1-1, manual operation system, electric pump 5 and oil cylinder 2 form, the hydraulic fluid port of fuel tank 1 communicates with oil main line 1-1 mono-end, manual operation system is comprised of manual pump 3 and Manual relief valve 4, the oil inlet of manual pump 3 and oil outlet communicate with the oil inlet of oil main line 1-1 and fuel tank 1 by A pipeline 3-1 and B pipeline 3-2 respectively, on A pipeline 3-1 and B pipeline 3-2, be respectively equipped with A check valve 3-3 and B check valve 3-4, on B pipeline 3-2, have drain tap, the drain tap of B pipeline 3-2 communicates with fuel tank 1 by C pipeline 3-5, C pipeline 3-5 is provided with Manual relief valve 4, the import of electric pump 5 and outlet communicate with fuel tank 1 and oil main line 1-1 by D pipeline 5-1 and E pipeline 5-2 respectively, on E pipeline 5-2, be respectively equipped with C check valve 5-3 and arm 5-4, arm 5-4 two ends communicate with E pipeline 5-2 and fuel tank 1 respectively, arm 5-4 is provided with by pass valve 5-5.
Principle of work:
1, hand hoisting: close Manual relief valve 4, utilize the operating handle on manual pump 3 that oil is pumped into the little pumping cylinder of manual pump 3 by B check valve 3-4 from fuel tank 1 warp, now A check valve 3-3, C check valve 5-3 close automatically.Then suppress the operating handle on manual pump 3, oil enters by A check valve 3-3 the operating cylinder that oil cylinder 2(is fork truck, and following oil cylinder 2 all can be defaulted as operating cylinder), now B check valve 3-4, C check valve 5-3 close automatically, and weight is raised.Open Manual relief valve 4, oil is got back to fuel tank 1 from oil cylinder 2 by Manual relief valve 4, and weight is lowered by, and now check valve A check valve 3-3, B check valve 3-4, C check valve 5-3 close automatically.When weight rose to set maximum height, the interior oil of oil cylinder 2 can flow back in fuel tank 1 by the little oilhole on plunger rod automatically.
2, electric hoist: close Manual relief valve 4, start electric pump 5(or the machine operation that switches on power, the driven gear pump work) oil is passed through check valve C check valve 5-3 suction oil cylinder 2 from fuel tank 1, now check valve A check valve 3-3, B check valve 3-4 close automatically.Weight is raised.Open Manual relief valve 4, oil is got back to fuel tank 1 from oil cylinder 2 by Manual relief valve 4, and weight is lowered by, and now check valve A check valve 3-3, B check valve 3-4, C check valve 5-3 close automatically.When weight rose to set maximum height, the interior oil of oil cylinder 2 can flow back into fuel tank 1 by the little oilhole on plunger rod automatically.
Hand hoisting and electric hoist mutually noninterfere, both can control weight by Manual relief valve 4 off-loads and descend.Electric hoist can be controlled weight decline (unloading electromagnetic valve can be installed as customer requirement) by the unloading electromagnetic valve off-load.
